I've also heard reports of people complaining about connection problems. Interestingly, have a look at this.

Battery life: I also think it's reasonable to expect that with all those features turned off, you should get a weekend's worth of standby time out of the thing. Assuming you weren't using it to surf and talk the whole time, of course. I don't know what its specs actually are, though.

Agreed that repositioning the software icons after an update is a pain. I'm sure that's something that everyone complains about and that they're going to fix eventually.

Switch: I happen to really like that switch. I like being able to check it for its silent-mode without having to pull it out of my pocket and punch buttons, like I would have needed to do with my old phone. If you get one of those rubberized sleeves for the thing, the switch will be recessed more and will be less likely to accidentally get moved. But like you said, that's another £30.
